"The planet Earth has been photographed by satellites in outer space"
"There is nothing left to be discovered except how to use what has been found.
The people who do this are called inventors."
Honestly, Alexander Graham Bell invented the telephone, but who invented the pay phone? No one had intended to find Florida. Ponce deLeon was looking for the Fountain of Youth not a state that serves no use greater than commercial trade, a second rate television series and breeding mosquitoes.
By the way, does anyone remember the second, fifth or tenth person to walk on the moon?
Will anyone remember that small step of the fiftieth astronaut to stroll on that rock in space?
The answer is that it's unlikely or else we wouldn't need plaques and mementos to remind us who they were.
Discover yourself, it's much more fulfilling.
